31. In addition to Rayleigh waves, some other types of surface acoustic waves ( SAW ), e . g. 32. Fig . 15A shows the schematic of a standing surface acoustic waves ( SSAW )-based cell enrichment device. 33. They developed Surface acoustic wave electronic filters which had many applications, including mobile phones when they later emerged. 34. This would be likely to be accomplished by acoustic wave communication, or using wires composed of single electrons. 35. A surface acoustic wave pressure sensor simply replaces the diaphragm with a piezoelectric substrate patterned with interdigitated electrodes. 36. At the labium the jet oscillation results in a generation of acoustic waves , which maintain the pipe oscillation. 37. It is possible to design linear analogue mechanical filters using mechanical components which filter mechanical vibrations or acoustic waves . 38. :: : : : The bigger concern is reflecting acoustic waves from the engines, which can damage the rocket. 39. A schematic of the standing surface acoustic wave ( SSAW ) focusing device is shown in Fig . 5. 40. A hypothetical dolphin mathematician might define " 1 " and " 2 " in terms of acoustic wave forms.
